Stained teeth in toddler

Paula

Hello, my son has really bad stains on his teeth. As soon as the teeth come out a couple of days later they are stained just like the rest of them.

We brush twice a day and have been since his teeth came out. He doesn't eat sweets or drink juice as I am scared they are gonna get worse.

We have been to the dentist a few times however they do not know why these stains appear, they just said they are not affecting his teeth only the look of them .

From what the dentist said they may be able to clean them when he will be a bit older and he will allow them to do it.

I used to have really bad teeth when I was little, but not as stained as his. Mine are really healthy now but I wouldn't want him to be bullied because of his teeth when he starts going to school.

Anyone else seen this before or knows of any way to treat or at least stop it from spreading?

Thanks a lot
